Description

Scale breaking roller changing operation vehicle and working method thereof

Technical Field

The invention belongs to the technical field of replacement of scale breaking rollers of derusters, and particularly relates to a scale breaking roller replacement work vehicle and a working method thereof.

Background

The steel plate is produced and often needs to pass a period of time to come to practical use, and in this period of time, because of steel plate self attribute reason can lead to the steel plate surface to rust, influences practical use, therefore need to carry out the rust cleaning to the steel plate before carrying out metal product processing with the steel plate and handle.

The prior method for removing rust on the surface of a steel plate is generally an acid pickling rust removal method. The principle is that the chemical reaction between acid in the acid washing solution and metal oxide is utilized to dissolve the metal oxide, so as to remove the rust and dirt on the surface of the steel. However, after the steel plate is pickled and derusted, a large amount of clear water is required for cleaning and passivating, and a large amount of waste water, waste acid and acid mist formed by the steel plate cause environmental pollution. If not properly treated, the metal surface can be over-etched to form pits. Under the severe situation of haze, river pollution and land pollution on ten surfaces in various places and the environmental protection pressure of public opinion, the national strong pollution control has more and more strong decisions. For enterprises still adopting the pickling process for rust removal, the environmental protection pressure is getting larger and larger. The method selects new environment-friendly derusting process equipment as soon as possible, and is in the very beginning.

There are also some physical rust removing ways, and the rust removing and polishing process for the surface of the steel plate in the technical field adopts a disc brush or abrasive belt rust removing mechanical device at present, but in practice, on one hand, the rust removing way has poor rust removing quality and low rust removing efficiency and cannot completely clean the surface of the steel plate; on the other hand, when the disc brush or the abrasive belt is worn and needs to be replaced, the manual operation is often needed for a long time, and time and labor are wasted.

The scale breaking roller is formed with a grinding brush rod made of nylon or diamond materials along the circumferential direction, and the grinding brush rod is gradually abraded in use, so that roller replacement operation is needed, manual assistance is needed before, time and labor are wasted, and efficiency is low.

The diameter of the external gear 1332 is equal to that of the gear shaft 1337; the external gear 1332 is a comb gear, and sparse teeth 13320 are circumferentially distributed on the periphery of the external gear 1332, that is, the number of the teeth 13320 is one half or one quarter of the sum of the length and the length of the internal gear 1331; preferably: the sum of the number of long teeth 13311 and short teeth 13312 on the internal gear is equal to twice the number of teeth 13320 of the external gear 1332, e.g., the number of long and short teeth of the internal gear totals 44, while the number of teeth 13320 of the external gear is 22.
